Daily supplementation with 650 mg of a proprietary blend of Sphaeranthus indicus and Mangifera indica extracts (LI12542F6) for 56 days significantly increases muscle strength, endurance, and lean mass in young, recreationally active males undergoing resistance training.

If you are a young male who lifts weights regularly, taking 650 mg of this specific herbal blend (LI12542F6) daily for about 8 weeks, alongside your normal training, may help you lift heavier weights and last longer on cardio compared to taking a placebo. It also appeared to increase lean muscle mass and improve hormone profiles (higher testosterone, lower cortisol) without causing side effects in this study.

Fifty-six days supplementation of LI12542F6 significantly improved baseline bench press (P < 0.0001), leg press (P < 0.0001), handgrip strength (P < 0.0006), number of repetitions (P < 0.0001), and time to exhaustion (P < 0.0008), compared to placebo.
